$15. Girl Tech IM-ME Pager Turned Into - a Spectrum Analyzer; a Police Radio Jammer...

This isn’t something we’d encourage our readers to do, but it’s pretty fascinating that a seemingly innocuous toy has such power. 

The IM-ME is a small electronic toy made by Girl Tech that’s intended to be used as a sort of imitation cell phone, allowing users to send wireless messages to each other. 

Unfortunately, a hacker named Travis Goodspeed discovered that you can use the hardware to roam frequencies freely and even decode the metadata that prefixes radio communications, allowing a listener to identify both parties on the call. 

You can also use the thing as a spectrum analyzer and many other unintended purposes... such as jamming. (more) (video on P25)
